METHOD FOR PRODUCING CARBONYL FLUORIDE AND HEXAFLUOROPROPYLENE OXIDE

摘要

Disclosed is a method for efficiently jointly producing carbonyl fluoride and hexafluoropropylene oxide. Specifically disclosed is a method for producing carbonyl fluoride and hexafluoropropylene oxide wherein a step (a)) for obtaining a first mixture containing hexafluoropropylene oxide, from the oxidation of hexafluoropropylene by oxygen, and an oligomer represented by the general formula CF3O(CF2O)n-R (wherein, -R indicates -COF, -OCOF or -CF2COF, and n indicates an integer of 0 - 50) and a step (b)) for obtaining a second mixture containing carbonyl fluoride and hexafluoropropylene oxide by thermal decomposition of the oligomer in the presence of the hexafluoropropylene oxide are carried out.
